The key includes: a body formed in a transversely elongated configuration elongated in a first direction; and a first stem positioned on one end side of the body in the first direction and extending along a third direction which is substantially perpendicular to the first direction and a second direction which is a protruding direction of the key from the housing. The housing includes: a biasing member for biasing the key in the second direction; and a first restricting portion positioned on the second direction side with respect to the first stem for engaging with the first stem biased by the biasing member. ## Claims ### Claim 1 A controller, comprising: a housing; and at least one key provided for protruding and retreating movement on the housing; the key comprising: a body formed in a transversely elongated configuration elongated in a first direction; and a first stem positioned on one end side of the body in the first direction and extending along a third direction which is substantially perpendicular to the first direction and a second direction which is a protruding direction of the key from the housing, and the housing comprising: a biasing member for biasing the key in the second direction; and a first restricting portion positioned on the second direction side with respect to the first stem for engaging with the first stem biased by the biasing member, wherein one of the key and the housing has a second stem positioned on the other end side of the first direction and extending in the third direction while the other of the key and the housing has a guide portion which sandwiches an end of the second stem for guiding movement of the second stem in the second direction and a second restricting portion for engaging with the second stem biased by the biasing member. ### Claim 2 (depends on 1) The controller according to claim 1, wherein the housing has the guide portion and the key has the second stem. ### Claim 3 (depends on 2) The controller according to claim 2, wherein the housing has an elongated hole which has an end edge defined by the guide portion and the second restricting portion and in which the second stem is inserted. ### Claim 4 (depends on 2) The controller according to claim 2, wherein at least one of the first restricting portion, second restricting portion and guide portion is provided on the third direction side and the opposite side to the third direction side with the key sandwiched therebetween. ### Claim 5 (depends on 1) The controller according to claim 1, wherein the first restricting portion is erected uprightly along the first direction from the inner face of the housing and is formed integrally with the housing. ### Claim 6 (depends on 1) The controller according to claim 1, wherein the housing has a front face, a rear face and a side face for connecting the front face and the rear face to each other and is formed in a substantially flattened configuration having a substantially oval shape as viewed in front elevation; and the key is disposed at least at one of the opposite ends in a leftward and rightward direction of the side face which is positioned at an upper location when the housing is grasped so that the first direction coincides with the leftward and rightward direction. ### Claim 7 (depends on 6) The controller according to claim 6, wherein the second stem is disposed at a position rather near to the center of the side face which is positioned at the upper location. ### Claim 8 (depends on 6) The controller according to claim 6, wherein the key is disposed so as to extend between and over the side face positioned at the upper location and a different side face which is contiguous to the side face, and an upper face of the key has a first face extending along the side face positioned at the upper location and a second face extending along the different side face. ### Claim 9 A portable electronic apparatus, comprising: a controller including a housing, and at least one key provided for protruding and retreating movement on the housing, the key comprising: a body formed in a transversely elongated configuration elongated in a first direction, and a first stem positioned on one end side of the body in the first direction and extending along a third direction which is substantially perpendicular to the first direction and a second direction which is a protruding direction of the key from the housing, and the housing comprising: a biasing member for biasing the key in the second direction; and a first restricting portion positioned on the second direction side with respect to the first stem for engaging with the first stem biased by the biasing member, wherein one of the key and the housing has a second stem positioned on the other end side of the first direction and extending in the third direction while the other of the key and the housing has a guide portion which sandwiches an end of the second stem for guiding movement of the second stem in the second direction and a second restricting portion for engaging with the second stem biased by the biasing member.
