Is composed of two and each chain is driven by sprockets 3-6. The driving force is transmitted from the motor 7 to the sprockets 3 to 6 through the clutch. One of the chains 2 moves a total of 14 hangers 8 (8a to 8n) in the direction of arrow A,
The other chain moves the selector 9 in the direction of arrow A or B. The moving direction of the chain is determined depending on whether the motor 7 is normally rotated or reversely rotated. Reflective optical sensor 12
Are provided in the selector 9 so as to move in conjunction with the selector 9.

When the selector 9 is at the uppermost position of the tubular coin storage tray 1 as shown in the drawing, the optical sensor 12 first detects whether or not there is a tubular coin in the storage tray, and if there is a tubular coin, When the chain 2 that moves the storage tray to the position indicated by the dotted line in the figure and moves the hanger 8 in this state moves in the direction of arrow A, the hanger 8a.
The coins are sequentially gripped by 8n. Hanger 8a
When three hangers of ~ 8c pass the position of the tubular coin storage tray moved forward, a total of three tubular coins are taken out, and when four hangers of 8a-8d pass, a total of four The tubular coin will be taken out. After taking out the specified number of cylinder coins in this way, return the cylinder coin storage tray that was moved forward to the original position, drive the chain to move the hanger again, and the cylinder gripped by the hanger. The coins are sequentially carried to the discharging unit 10.

FIG. 3 is a partial structural view of the peripheral portion of the selector 9.
This embodiment will be described more specifically with reference to FIG. The selector 9 is at a position for selecting the cylindrical coin storage tray C. The optical sensor 12 irradiates light to a cylindrical coin, which is assumed to be present in the cylindrical coin storage tray, from the light emitting portion of the optical sensor in order to detect the presence or absence of the cylindrical coin. As will be described later, this light enters the tray by passing through a window provided at the front end of the tubular coin storage tray. If there is a tubular coin, the reflected light from the tubular coin passes through the window portion, and the light is received by the light receiving portion of the optical sensor 12 to detect the presence of the tubular coin. Next, the selector 9 is pushed by a kicker plate (not shown) to rotate about the fulcrum P and release the lock lever 13. When the lock lever 13 is released, the cylindrical coin storage tray C slides out, moves forward, and stops at a fixed position. Next, as described above, the tubular coin in the tubular coin storage tray from which the hanger 8 has been pulled out is placed in the recess and carried to the discharge port. After the tubular coin at a predetermined position is taken out, the tubular coin storage tray is returned to the original position by a pusher plate (not shown).
