Monitoring device for the coin container of a coin collecting mechanism

A monitoring device for the coin container of a coin collecting mechanism, comprising a coin container (1), two separate contact members (9, 109), which project into said container (1), the spacing of the two contact members (9, 109) which are isolated from one another being greater than the diameter of the coins that are to be collected and at least one of the two contact members being arranged in the upper part of the container (1) at a specific filling height, so that the coins collected in the container (1) establish a connection at said specific filling height between said two contact members (9, 109), an oscillator circuit (17), a transformer (14) having at least two windings (15,16), said contact members (9, 109) being connected to the opposite ends of one (15) of the two windings of said transformer (14), and the other winding (16) of said two windings forming part of the oscillator circuit (17) in such a way that the oscillations thereof are suspended when said two contact members (9, 109) are connected in circuit by the coins, and a signal circuit (26, 32) connected to said oscillator circuit (17) to emit a signal which indicates whether the oscillator (17) is oscillating.

A monitoring device for the coin container of a coin collecting mechanism, comprising a coin container which is metallic and is exchangeable, an oscillator circuit (37), a self-induction coil (10) connected to said oscillator circuit (37), said coil (10) so arranged that one of the walls (11) of the coin container (1) is adapted to extend through the coil field and to influence the coil field in such a way that said oscillator circuit (37) is oscillating or not oscillating depending on whether the coin container (1) is present, a signal circuit (38, 39, 40) connected to said oscillator circuit (37), which emits a signal blocking the coin collecting mechanism when the coin container (1) is not present.

A monitoring device for the coin container of a coin collecting mechanism, comprising a coin container (1) which is exchangeable, first detection means (1, 9, 17) having contact means (1, 9), between which the coins collected in the container (1) are adapted to establish a connection at a specific filling height, a first signal circuit (26, 32) connected to said first detection means (1, 9, 17) to emit a first signal which indicates whether the contact means (1, 9) are connected by the coins or not, second detection means (10, 37) having sensing means (10) so arranged that one of the walls (11) of the coin container (1) is adapted to influence said sensing means (10), a second signal circuit (38, 39) connected to said second detection means (10, 37) to emit a second signal which indicates whether the coin container (1) is present, and a logic circuit, to which said first and second signals from said first and said second signal circuit (26, 32;

• 38, 39) are fed and which emits a signal bolcking the coin collecting mechanism when the first signal indicates that the contact means (1, 9) are connected by the coins or the second signal indicates that the coin container (1) is not present.
