Description

[Detailed Description of the Invention] This invention relates to a coin storage and return device useful for a coin processing mechanism in a pay-to-use device such as a public telephone, and particularly relates to the structure of a storage operation section.

The basic structure of the coin processing mechanism of a public telephone is a series of structures consisting of a coin input slot, a coin sorting track device, a coin storage track device, a coin storage/return device, and a coin return slot.・
Each operation of accumulation, storage, and return is automatically performed by signal operation force.

Specifically, in the coin storage operation, after the handset is removed from the hook and a call is started, a predetermined number of coins from among the coins accumulated in the coin accumulation orbit are dropped into the storage safe every predetermined call time period. It is becoming more and more crowded.

In this case, since the call time limit is determined according to the charge per coin, only one coin is stored at each time signal, but depending on the use of the telephone, multiple coins may be stored. In some cases, a call time limit for a coin charge is determined, and in this case, it becomes necessary to store and operate a predetermined plurality of coins during each call time limit.

In order to adapt to this, the structure of conventional telephones is
A structure is adopted in which the number of sheets to be dropped in one storage operation can be variably set by electrical means, and a circuit for the number of sheets to be stored corresponding to the application is set at the time of assembly.

However, such conventional countermeasures have the disadvantage that an extra circuit for setting the number of stored cards must be provided, which increases the cost of the telephone.

In addition, conventionally, in Fig. 1 of JP-A-49-115397, there is a storage lever (6 in the drawing) that opens and closes the lower end of the coin accumulation track (5 in the same publication) in the middle of the coin accumulation track (5 in the drawing in the same publication). ), the pin-shaped coin storage number control lever (7) is projected, but the configuration shown in Figure 1 of this publication does not allow for changes in the number of coins to be used or the diameter size. It is not possible to change the position of the control lever (7).

Further, FIGS. 2 to 4 of the above-mentioned publication show a configuration in which the coin storage number control lever (35) is used as a link mechanism that presses the flat surface of the coins, and its position is variable up and down. Due to the change in the position of the control lever, the structure for adjusting the position of the actuation means of the control lever becomes complicated, and furthermore, the control lever and the coin storage lever that opens and closes the lower end opening of the coin storage track are operated by separate mechanisms. Because of this structure, there are problems such as that it is troublesome to adjust the timing of each lever in conjunction with the above-mentioned position adjustment. Furthermore, the function of the control lever to receive accumulated coins is not reliable.

The present invention has been developed in view of the above points, and the purpose of the present invention is to perform a simple operation of selecting and moving the mounting position of the bracket as a subassembly of the storage operation member, and to improve the operation during coin storage. It is an object of the present invention to provide a coin storage and return device which is capable of changing the number of coins dropped and does not require adjustment of the position of each operating member when adjusting the movement of the bracket.

The structure of the present invention to achieve the above purpose is as follows:
A coin accumulation track 2, which is a coin track formed substantially vertically along the coin track plate 1, and is configured to accumulate coins falling from a coin sorting track 4 in a stacked state in one row in the diametrical direction. and a pivot 3 disposed substantially parallel to the coin accumulation track 2.
A coin storage lever 12 is a coin storage lever 12 made of a flapper-shaped frame plate that is swingably attached to the coin storage lever 12, and a hanging plate 12a extending from the coin storage lever swinging portion extends in a direction that crosses the lower end opening of the storage track 2. a coin storage lever 12 that opens and closes the opening by moving the lever; a bracket 15 that is removably fastened to the coin track plate 1; The coin storage lever 12 is moved against the repulsive force of the spring and the above-mentioned hanging plate 1 is moved.
2a is pushed and driven in a direction across the lower end opening of the storage track 2, and a coin receiving pin 23 protruding from its swinging portion is moved into and out of the middle of the storage track 2. control lever 21
, an operation drive means 19 attached to the bracket 15 and swingingly driving the storage control lever 21 based on a signal; and a plurality of upper and lower stages on the plate surface of the coin track plate 1 along the coin accumulation track 2. Mounting holes 25 arranged at each height of
The bracket 15 is selectively fastened, and the height of each stage is such that the coin receiving pin 23 protruding from the storage control lever 21 is piled up in the storage track. The coin storage and return device is characterized in that it is provided with mounting holes 25 that are set to correspond to the heights of the coins.

According to the above structure of the present invention, by selecting the mounting hole 25 and mounting the bracket 15, the insertion position of the coin receiving pin 23 protruding from the storage control lever 21 on the bracket 15 is changed. By changing the number of accumulated coins received by the pin 23, the number of stored coins for each operation is changed.

At this time, the operation driving means 1 of the storage control lever 21
Since the pin 9 is also provided on the bracket 15 and moves together, the pin 23
There is no variation in the displacement stroke amount, and the coin can be received and passed without any trouble.

Further, a part of the storage control lever 21 on the bracket 15 pushes and drives the coin storage lever 12 that is integrated with the hanging plate 12a. The driving point of action is displaced almost only in the vertical direction as the mounting position of the bracket 15 is changed, and is always located on a line equidistant from the pivot center line (pivot 3) of the coin storage lever 12. Therefore,
Coin storage lever 1 by this storage control lever 21
The swing control of No. 2 and its stroke are also constant regardless of changes in the height position of the storage control lever 21, and there is no need to make adjustments.

Hereinafter, the present invention will be explained based on an illustrated embodiment.

As shown in FIGS. 1 to 4, the storage and return device of the embodiment is arranged so as to surround a coin storage track 2 formed in the lower left half of the front side (the front side in FIG. 1) of a coin track plate 1. The coin track plate 1, which consists of a rectangular plate with left and right flanges, is erected inside the phone case, being pivotally connected to a pivot 3 vertically suspended inside the phone case (not shown). .

Therefore, the coins input from the coin input port A of the track plate 1 along the front surface of the track plate 1 pass through the coin sorting track 4, and after the defective coins are removed to the lower space, the normal coins that have passed through the coin sorting track 4 are removed. The particles fall into the storage track 2, pile up in a row in the diametrical direction, and stay there.

Thereafter, a predetermined number of accumulated coins C (in the illustrated case, one coin each time) are dropped into the storage passage 5 for each predetermined telephone time period, and are discharged into the storage safe below, and are retained after the call ends. The remaining coin C is
After being dropped all at once into a space B on the front of the track plate 1, the coins are discharged into a coin return slot R.

By the way, the storage track 2 formed in the vertical direction along the track plate 1 has an end plate 6 made of a vertically long plate.
and a stationary side plate 8 which overlaps with the end plate 6 and is fastened to the raceway plate 1 with upper and lower screws 7, and is therefore a space on one side of the storage track 2 (on the right side in Figure 1). The long edge of is open.

Note that the opening edge is provided with an overhang slope, and a cross-sectional space of the lower end 6a of the end plate 6 extending below the side plate 8 serves as the storage passage 5.

Next, a movable side plate 9 forming a side plate of the sorting track 4 is pivotally supported on the upper half of the pivot 3, and the same side plate 9
is the raceway plate 1 due to the pushing force of the torque spring 10.
A return lever 11 made of a U-shaped frame plate is pressed parallel to the left half of the same side plate 9 and is integrally connected to the lower left half of the same side plate 9. At the same time, the tip of the partition plate 11a formed over the swinging end of the lever 11 has entered the hole 1a bored in the track plate 1 along the opening edge of the storage track 2. , so that the edge opening of the storage track 2 is
It is designed to be opened and closed by swinging the return lever 11.

In addition, a swinging base of a storage lever 12 made of a flapper frame plate disposed along the lower part of the back side of the track plate 1 is pivotally supported at the lower part of the pivot 3.
A hanging plate 12a extending from the inclined lower end of the storage lever 12 passes forward through the diagonal escape hole 1b of the track plate 1.

The storage lever 12 is in a counterclockwise swinging position in FIG. 3 due to the backward pushing bias of the torque spring 13 wound around the pivot shaft 3, and in this habitual normal position, the holding lever 12a is Although the lower end of the track 2 is closed, in the swinging position (see FIG. 5) in which the storage control lever 14 (details will be described later) is driven clockwise in FIG. The slit 12b faces the storage track 2 and operates to communicate the track 2 with the storage road 5.

Next, on the lower left side of the back surface of the raceway plate 1, a floating table plate-shaped bracket 15 is fastened with mounting screws 16 at two places, on the top side and the side side, and is attached to the inner end of the bracket 15. An L-shaped support plate 17 is fixed with screws 18, and a solenoid 19 that is energized based on a storage activation signal is vertically attached to the horizontal base of the support plate 17.

Furthermore, a support shaft 20 horizontally suspended at the upper end of the support plate 17
, a storage control lever 21 consisting of a rectangular frame whose top plate is made of a magnetic piece is pivoted at its upper end while surrounding the support plate 17, and a part of the lower side of the control lever 21 is pivoted. , the base end of the actuating piece 21a hanging downward is fixed, and the actuating piece 21a
A roller 22 that presses the storage lever 12 from the back is pivotally attached to the lower end of 1a, and an actuating piece 2
On the front side in the middle of 1a, there is a pin 23 for coin receiving.
The pin 23 is inserted into the lower hollow part 24 of the upper and lower two hollow parts 24 which are recessed in the middle of the escape hole 1a and each side edge of the fixed side plate 8. Intrusion/
They are in a tangential relationship of exit and movement.

The positions of the empty spaces 24 in the upper and lower two stages are as follows:
It is formed to a height that corresponds to the middle position between the second and third coin from the bottom in the track 2, and the middle position between the lowest coin and the second coin.

In addition, near the left end of the raceway plate 1, in addition to two screw holes into which the bracket tightening screws 16 are screwed, two screw holes 25 are drilled in corresponding positions above the screw holes. When the bracket 15 is fastened to the upper screw hole 25, the pin 23 faces the upper hollow part 24, and in this assembled state, the pushing roller 22 is attached to the storage lever 12.
The storage lever 12 is operated and driven in the same manner.

Next, the storage operation of the storage and return device of the embodiment configured as described above will be explained.

After starting a call or continuing a call, when a predetermined call time period elapses, solenoid 1 is activated from the call control circuit.
9 is automatically energized for a certain period of time, first, when energizing, the control lever 21 is turned on as shown in FIG.
swings clockwise to push and move the swinging portion of the storage lever 12 forward, and in this moving position, the pin 2
3 enters the accumulation orbit 2, 2 from below
At the same time as receiving the second or more coins C, the slits 12b of the hanging plate 12a face each other and open the lower end of the track 2, thereby causing the lowest coin C to fall into the storage passage 5.

Next, when the energization to the solenoid 19 is stopped,
As the storage lever 12 returns to its original swinging position (FIG. 4) due to the elasticity of the return spring 13, the second or more coins C are released from the pin 23 and move downward within the track 2. The coin moves and stays on the hanging plate 12a, and in this way, one coin is stored in the storage safe each time the storage operation is performed.

By the way, if the purpose of the telephone changes and it becomes necessary to store two telephones, it is sufficient to replace the bracket 15 with the screw hole 25 on the upper stage.If assembled in this way, the operation will be performed in the same manner as described above. The third or more coin C from the bottom is once received by the pin 23, and the two coins C from the bottom are dropped from the slit 12b of the hanging plate into the storage passage 5. Two coins are stored when the storage is activated.

In the configuration of the embodiment, in order to store a predetermined number of coins, such as three or more, screw holes for mounting the brackets must be drilled at a predetermined number of stages, and the control lever 21 must be pushed. If the abutting surface of the storage lever 12 that the roller 22 abuts is stretched upward and formed into a stretch, it becomes possible to drop a plurality of sheets as in the case of assembly described above.

According to the coin storage and return device according to the present invention, the mounting holes 25 are provided in advance at multiple heights on the coin raceway plate surface.
The height of the receiving pin 23 is made variable by drilling the bracket 15 that supports the storage control lever 21 and tightening the mounting position of the bracket 15 that supports the storage control lever 21 to the selected mounting hole 25. It becomes possible to easily change the number of stored coins during storage operation without increasing costs, and this has the effect of increasing the adaptability of use in pay-to-use equipment such as public telephones.

In addition, in the present invention, due to the above-described structure and operation, all adjustments can be made only by moving the bracket 15, that is, the receiving pin 23 can be adjusted.
There is no need to adjust the displacement stroke amount of the coin storage lever 12 and the operation timing and stroke amount of the coin storage lever 12 having the hanging plate 12a that opens and closes the lower end opening of the coin storage track 2, making adjustment of its movement extremely easy. There is.
