A prior art bill handling apparatus includes a bill validator for validating a bill and a stacker for storing bills considered valid by the bill validator. For example, Japanese Utility Model Disclosure No. 58-117568 published August 11, 1983 discloses a bill validator with which a stacker is integrally incorporated to form a shorter passageway for bill in order to manufacture the apparatus in smaller size. Also, Japanese Patent Publication No. 3-101567 published February 13, 1991 demonstrates a bill apparatus which comprises a casing; a validator disposed within the casing for validating a bill; a stacker for accumulating bills considered genuine by the validator; a L-shaped passageway formed through the validator and stacker; and a pusher for forcing a bill in the passageway into the stacker. In this prior art reference, the stacker is rotatably attached to the case to reduce the depth of the casing for the small sized apparatus. Provided in prior art bill handling apparatus to validate a bill is a validator which is firmly and incommutably secured to a stacker so that the bill handling apparatus itself should be exchanged when a different kind of bills should be validated or when the validator has broken down. EP 0 531 983 A 1 discloses a bill handling apparatus according to the preamble-of claim 1. This known bill handling apparatus comprises bill stacker means adapted for detachable attachment to the validator sensing means at both an up-stacking position and a down-stacking position. At the up-stacking position the stacker means is arranged at a position higher than the validator sensing means whereas at the down-stacking position the stacker means is arranged at a position lower than the validator sensing means. The stacker means is detachably attached by a mechanical attaching mechanism. Accordingly, an object of the present invention is to provide a bill handling apparatus which includes a validator sensing means easily and exchangeably attached thereto and which can validate a different kind of bills by exchanging the validator sensing means without the need to exchange the complete bill handling apparatus. The bill handling apparatus according to the present invention comprises connector means for electrically connecting said sensor means in said validator sensing means with said validator control means in said frame after said validator sensing means is moved from said frame, whereby output of said validator sensing means is forwarded to said validator control means in said frame through said connector means. Advantageous embodiments of the invention are disclosed in claims 2 to 9. The bill handling apparatus according to the invention produces the effect that the validator sensing means can easily be exchanged and that different kinds of bills can be validated by exchange of the validator sensor means with another one while using the same frame, validator control means and stacker means. According to an advantageous embodiment of the invention, the bill handling apparatus further comprises power transmission means situated in the frame with the conveyer means situated in the validator sensing means, said power transmission means comprising a drive gear rotatably supported on the frame and a follower gear rotatably mounted on the validator sensing means for engagement with the drive gear. This embodiment produces the effect that when the validator sensing means is connected to the stacker means by the coupling means in the condition that the passageways of the validator sensing means and stacker means are aligned with each other the sensor means is electrically connected with the validator control means position in the frame through the connector means, and the conveyer means in the validator sensor means is drivingly connected with the drive means in the frame through the power transmission means.

Referring now to the accompanying drawings, an embodiment according to the present invention will be described hereinafter in reference to Figs. 1 to 8. As shown in Figs. 1 to 5, the bill handling apparatus 1 according to the present invention, comprises validator sensing means 2 for validating a bill inserted into the apparatus 1; stacker means 3 for storing a bill in response to an output from the validator sensing means 2 when the bill is considered genuine by the validator sensing means 2; a frame 4 for supporting the stacker means 3; coupling means 10 for detachably supporting the validator sensing means 2. The validator sensing means 2 comprises a conveyer means 20 for providing the passageway 21 and sensor means 22 disposed adjacent to the passageway 21 and validator control means 8 positioned in the frame 4 as shown in Fig. 4. The conveyer means 20 comprises a follower gear 23; a pulley 24 drivingly connected with the follower gear 23; at least a belt 26 wound around the pulleys 24, 25; and rollers 27, 28 rotatably mounted on the validator sensing means 2 opposite respectively to the pulleys 24, 25. The sensor means 22 includes a magnetic sensor 22a to detect magnetic features from ferrous ink on a bill, and an optical sensor 22b to detect optical features of a bill from a light beam reflected on a surface of the bill or permeated through the bill. Disposed adjacent to an inlet 2a of the validator sensing means 2 is an optical sensor not shown which detects insertion of a bill 5 into the inlet 2 to produce a trigger signal for activation of the conveyer means 20. As shown in Fig. 3, the coupling means 10 is provided between the validator sensing means 2 and frame 4 to removably support the validator sensing means 2 on the frame 4 so that the passageway 21 of the validator sensing means 2 is kept in aligned condition with an inlet 31a of the passageway 31 of the stacker means 31. The coupling means 10 includes guide means 13 provided in the frame 4 and a pair of pins 12 provided in the validator sensing means 2 in engaged relation to a pair of guide grooves 11 formed on opposite sides of the guide means 13. As illustrated in Fig. 7, the coupling means 10 comprises a stopper lever 49 rotatably provided in the frame 4 by a shaft 51; an abutment 46 formed in the validator sensing means 2 for engagement with the stopper lever 49; and a spring 47 for resiliently urging the stopper lever 49 toward the abutment 46 to keep the engagement between the stopper lever 49 and abutment 46. A slider 48 is slidably provided in the frame 4 to release the engagement of the stopper lever 49 with of the abutment 46 of the validator sensing means 2. The stacker means 3 is operated to store a bill 5 in response to an output of the validator sensing means 2 which has decided that the bill 5 is genuine. The stacker means 3 comprises a pusher 32 which forcibly pushes into a storage chamber 50 the bill 5 which is conveyed along the passageway 31. The pusher 32 has a push plate 33 in contact with the bill 5; two pairs of support links 34, 35 rotatably connected with the push plate 33 by pins 34a, 35a; and a press link 36 one end of which is rotatably connected by a pin 36a with approximately central portions of the support links 34, 35. The other end of the press link 36 is rotatably connected with a disk link 37 by a pin 37a so that the press link 36 can reciprocally move in the direction perpendicular to the passageway 31 during rotation of the disk link 37. An electric motor 41 is arranged in the frame 4 to operate drive means 6 which drives the conveyer means (not shown) in the stacker means 3 to travel the bill 5 along the passageway 31 in the frame 4, but detailed drawing is omitted. The drive means 6 comprises a pinion 42 mounted on an output shaft of the motor 41, a first gear 43 meshed with the pinion 42, a second gear 44 secured to the first gear 43, and a drive gear 45 in engaged relation to the second gear 44 and the follower gear 23. The drive gear 45 and follower gear 23 provides a power transmission and the follower gear 23. The drive gear 45 and follower gear 23 provides a power transmission means which drivingly connects the drive means 6 in the frame 4 with the conveyer means 20 in the validator sensing means 2. The drive gear 45 is rotatably supported on the frame 4, and the follower gear 23 is rotatably mounted on the validator sensing means 2. As shown in Fig. 4, provided between the validator sensing means 2 and frame 4 is connector means 60 which comprises a plug 61 provided in the validator sensing means 2 and a jack 62 in the frame 4 so that the plug 61 can be inserted into the jack 62 to electrically connect the sensor means 22 in the validator sensing means 2 with validator control means 8 in the frame 4. When the validator sensing means 2 is connected with the stacker means 3 by the coupling means 10, the passage-ways 21, 31 of the validator sensing means 2 and stacker means 3 are retained in the aligned condition to each other. Simultaneously, the drive gear 45 of the drive means 6 in the frame 4 and the follower gear 23 of the conveyer means 20 in the validator sensing means 2 are aligned to each other in a same plane. Also, the plug 61 of the validator sensing means 2 and the jack 62 in the frame 4, are positioned in a same plane. As understood from Fig. 4, the validator control means 8 comprises discriminating means 8a connected with the jack 62, and drive control means 8b connected with the discriminating means 8a to receive control signals from the discriminating means 8a. Also, the drive control means 8b is connected with a conveyer drive circuit 63 and a stacker drive circuit 64 to supply drive signals. In addition, the drive control means 8b is connected with an encoder 65 for recognition of moved position of the bill 5, a home position sensor 66 for detecting a retracted position of the push plate 33 and other sensors 67 so that the drive control means 8b may receive signals from the encoder 65 and sensors 66, 67. When the validator sensing means 2 is connected with the stacker means 3 by the coupling means 10 in the condition that the passageways 21, 31 of the validator sensing means 2 and stacker means 3 are in the aligned condition to each other, the sensor means 22 in the validator sensing means 2 can automatically and electrically be connected with the validator control means 8 through the connector means 60, and the conveyer means 20 in the validator sensing means 2 can automatically be connected with the drive means 6 in the frame 4 through the drive gear 45 of the drive means 6 in the frame 4 and the follower gear 23 of the conveyer means 20 to transmit driving power from the drive means 6 to the conveyer means 20. To exchange the validator sensing means 2 with another one, the slider 48 is manually pushed toward the stopper lever 49 so that the stopper lever 49 is rotated around the shaft 51 against the resilient force of the spring 47 to release the engagement of the stopper lever 49 from the abutment 46 of the validator sensing means 2. At this time, when the validator sensing means 2 is pulled before, the pins 12 moves along the guide grooves 11 of the coupling means 10 to finally remove the validator sensing means 2 outward from the frame 4 for exchange. When another validator sensing means 2 is attached instead to the frame 4, the pins 12 are received within the guide grooves 11 and the validator sensing means 2 is traveled inward and along the guide grooves 11 while the slider 48 is manually pushed. When the validator sensing means 2 is pushed along the guide grooves 11 to enough depth, manual force is removed from the slider 48. When a bill 5 is inserted into the inlet 2a of the validator sensing means 2, the insertion of the bill 5 is detected by operation of the above-mentioned optical sensor which then produces an output. The validator control means 8 receives the output from the optical sensor and activates the motor 41 to drive the drive means 6. Consequently, the pinion 42, the first and second gears 43, 44, the drive gear 45 and follower gear 23 are rotated in turn to drive the conveyer means 20 so that the bill 5 is carried into the validator sensing means 2. The validator control means 8 receives detection signals from the validator sensors 22a, 22b, and decides whether the bill 5 is genuine or not. When the validator control means 8 has decided that the bill 5 is not genuine, it drives the motor 41 in the reverse direction to return the bill 5 to the inlet 2a. When the validator control means 8 has decided that the bill 5 is genuine, it continues to produce the drive signal to the motor 41 in the forward direction so that the conveyer means 20 is activated to travel of the bill 5 through the passageways 21 and 31 beneath the push plate 33 of the pusher 32. At this stage, the disk link 37 is rotated and the press link 36 is forcibly moved downward so that the support links 34, 35 are rotated from the retracted position of Fig. 1 to the extended position of Fig. 8 to store bills in the storage chamber 50 in the accumulated condition. This embodiment of the instant invention produces the following effects: (1) The validator sensing means 2 can easily be exchanged. (2) The validator sensing means 2 without motor can be manufactured in light weight and small size for easy handling and maintenance. (3) Other kinds of bills can be validated by exchange of the validator sensing means 2 with another one. ROM (Read Only Memory) can be exchanged to alter the data processing for the discrimination of the bill (4) The single motor 41 is available to drive conveyer means 20 of the validator sensing means 2 and stacker means 3 to manufacture the bill handling apparatus 1 in small size and at reduced cost. Modes of the present invention may be varied in view of actual demands without limitation to the foregoing embodiment. For example, the conveyer means 20 and the disk link 37 can be driven by the single motor 41 in the different rotational direction. The pins 12 can be provided in the frame 4, while the guide means 13 can be provided in the validator sensing means 2 to receive the pins 12. Another motor than the motor 41 may be provided in the validator sensing means 2 to drive the conveyer means 20 by electric power supplied through the connector means 60 from power source. A part of the validator control means 8 may be disposed in the validator sensing means 2 not in the frame 4. As mentioned hereinbefore, the present invention realizes that validator sensing means 2 can easily be removed from the bill handling apparatus to replace with another one for easy maintenance and inspection of the validator sensing means 2. In addition, the bill handling apparatus can readily respond to validate other kinds of bills or change of model or to accommodate to the modified specification of design.
