System unit for adjusting operation of camera

#This application claims the priority of Japanese Patent Application Nos. 5-219090 and 5-219091 filed on Aug. 11, 1993, which are incorporated herein by reference.

#1. Field of the Invention

#The present invention relates to a system unit for adjusting the operation of a camera, and more particularly to the structure of a system for setting and adjusting operation conditions of a camera at the final stage of the process for manufacturing the camera.

#FIG. 1 shows the reverse side of a camera that is a portion of a system unit for adjusting the operation of a camera according to a first embodiment of the present invention;

#FIG. 2 is a cross sectional view of the film patrone chamber according to the first embodiment taken horizontally;

#FIG. 3 is an overall view of the adjustment system unit according to the first embodiment:

#FIG. 1 shows the reverse side of a camera serving as a portion of an adjustment system of the camera operation according to a first embodiment in a state where a reverse cover of the camera has been removed. As shown in FIG. 1, a camera 12 comprises a shutter button 13 and a finder 14, the camera 12 having an aperture 15 formed therein. Thus, a film is caused to move along an aperture surface 16 in the rear of the aperture 15. A film winding chamber 17 is disposed to the right of the aperture 15, while the film patrone chamber 18 is disposed to the left of the same. The film patrone chamber 18 comprises a semi-columnar wall member (housing) 19 having a plurality of film information detection contacts (DX contacts) 21 through holes 20 similarly to the conventional structure.

#FIG. 2 shows a horizontal cross section of the film patrone chamber 18. As shown in FIG. 2, the holes 20 are formed in the corner portion of the wall member 19 so that the DX contacts 21 project through the holes 20. Individually from the holes 20 for the DX contacts 21, plural pin receiving holes 22 are, in the vertical direction, formed in the wall member 19. The pin receiving holes 22 are formed in the front surface (in the front surface of the camera or in a surface running parallel to the aperture surface 16) of the film patrone chamber 18 in order to insert straight probe contact pins 24. The DX contacts 21 are connected to an elongate-spring-shape terminal plate 25. The terminal plate 25 is supported by a support portion 26 while being disposed in front of the pin receiving holes 22. Therefore, the probe contact pins 24, inserted through the pin receiving holes 22, are brought into contact with the terminal plate 25. Thus, the terminal plate 25 serves as the adjustment contact and also serves as a terminal for detecting the DX code.

#FIG. 3 shows the overall body of the system unit for adjusting the operation of a camera according to this embodiment. The camera 12 is secured to a receiving frame 29 in a state where a reverse cover 28 has been removed. A chassis (an attachment plate) 30 is disposed in the rear of the camera 12 while being guided by guide rails 31. A probe 32 having the contact pins 24 is attached to the chassis 30. The probe 32 is formed into a semi-columnar shape having a width which is the same as the width of the inlet portion of the film patrone chamber 18. The probe 32 has, at the leading portion thereof, a plurality of contact pins 24 formed in the vertical direction thereof. When the probe 32 is received by the film patrone chamber 18, the contact pins 24 are inserted into the pin receiving holes 22.
