[Example] Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 is an explanatory circuit diagram showing a coin-based switch mechanism of a toy according to an embodiment of the present invention, and FIG. 2 is a perspective view showing the internal mechanism of a toy vending machine using the switch mechanism of FIG. 1. , FIG. 3 is an external perspective view of a toy vending machine incorporating the internal mechanism shown in FIG. 2, FIG. FIG. 3 is a vertical cross-sectional view taken along the line shown in FIG. 3, and FIG. 6 is a vertical cross-sectional view taken along the line shown in FIG. 3, showing the change feeding mechanism.

In the vending machine toy 1 according to this embodiment, when a coin 2 is inserted into the input port 3, a canned waste 4 as a product comes out of the product takeout port 5, and at the same time change 6 comes out of the change return port 7. It is mainly composed of a switch mechanism 8 for input, a product dispensing mechanism 9 and a change dispensing mechanism 10 operated by the switch mechanism 8.

As shown in FIG. 1, the switch mechanism 8 is energized when a coin 2 is inserted into a contact 11 arranged in the coin insertion slot 3.
is made of an electrically conductive material for this purpose. For example, a metal item can be used, and here, a 100 yen coin is used. The contact 11 is composed of a fixed contact plate 11a and a movable contact plate 11b,
A coin 2 can be inserted between them, and one movable contact plate 11b is provided with a coin holding piece 11c that temporarily holds the coin 2.
Further, the contact 11 forms an initial movement circuit 13 of the motor 12, and when the coin 2 is inserted, the initial movement circuit 13 closes and becomes energized, power is supplied from the battery 14 to the motor 12, and the motor 12 starts the initial movement. (Figure 4) Further, as shown in FIG. 4, when the motor 12 performs an initial movement, the metal conductive cam 15 rotates and the energization maintenance mechanism is activated, closing the contact 17 of the energization maintenance circuit 16, and this energization maintenance circuit 16 is activated. It becomes energized and the initial operating circuit 1
3 is open, power is supplied to the motor 12 from the battery 14 for a certain period of time to maintain rotation of the motor 12. That is, the conductive cam 15 constitutes a movable contact, and the contact 17 is opened when the concave portion 15a formed in a part of the conductive cam 15 and the convex portion 18a formed on the fixed contact plate 18 are aligned.
opens, and the conductive cam 15 opens in conjunction with the rotation of the motor 12.
rotates, and the convex portion 18a of the contact plate 18 connects with the conductive cam 15.
The concave portion 15a contacts the outer peripheral surface of the convex portion 18a again.
Until it returns to the position, it is closed and energized. Specifically, as shown in FIG. 1, the conductive cam 15 is integrally fixed to the shaft 22 of a gear 21 that meshes with a gear 20a disposed coaxially with a gear 20 that meshes with a drive gear 19 of the motor 12. The conductive cam 15 is connected to the motor 12 through a gear group, and an initial movement circuit 13 is connected to the end of the same shaft 22 to which the conductive cam 15 is fixed.
A cam 23 for cutting the contact 11 is fixed. An engaging piece 26 for engaging the cam 23 is provided at a position corresponding to the cam 23 and protrudes from a shaft 25 that is rotatably supported by a sleeve 24.
b An engagement plate 28 that can come into contact with the protruding piece 27 at the lower part is provided. Note that 29 is a sliding contact that contacts the side surface of the conductive cam 15. Therefore, when the coin 2 is inserted into the slot 3, the fixed contact plate 11 of the contact 11
The coin 2 enters between the movable contact plate 11b and the coin 2, where it is temporarily held by the coin holding piece 11c, and in this state, the contact 11 closes and the motor 12
is energized and performs an initial movement, and this initial movement of the motor 12 causes the drive gear 19 and gears 20, 20 to
a, 21, the shaft 22 rotates to rotate the conductive cam 15. The contact 17 is closed by the rotation of the conductive cam 15, and when the shaft 22 further rotates in this state, the cam 23 contacts the engagement piece 26 and rotates it in the direction of the arrow. The integrated engagement plate 28 also rotates in the direction of the arrow and comes into contact with the protruding piece 27, pulling the lower part of the movable contact plate 11b in the direction of the arrow to open the space between the fixed contact plate 11a and the movable contact plate 11b and allowing the coin 2 to fall. . In this state, the contact 11 is open and power is not supplied to the motor 12 from the initial movement circuit 13, but since the contact 17 is closed due to the rotation of the conductive cam 15, the conductive cam 15 rotates once and returns to its original state. Until the motor 1 returns to the position, the energization maintaining circuit 16 keeps the motor 1
Power is supplied to 2, and rotation is maintained.

The product feed mechanism 9 is activated by a switch mechanism 8 when a coin 2 is inserted, and feeds one canned youth 4 to the product takeout port 5.
Crank 3 that operates and transmits rotation by contact with
1, and an extrusion rod 32 as a dispensing member that performs a sliding operation via the crank 31 to extrude a can 4 as a product.
The cam 30 is connected to the drive gear 19 and the gears 20, 20a,
It is mounted on a shaft 22 that is coaxial with the rotating conductive cam 15 via a shaft 21, and rotates once for every rotation of the conductive cam 15. The crank 31 has a central portion rotatably attached to a fixed shaft 33, and an upper portion attached to a spring 3.
4 in the pulling direction (the pushing direction of the pushing rod 32), so that the lower part corresponds to the cam 30 and can come into contact with it. The extrusion rod 32 is fitted into the sleeve 35 and causes the pin 37 to protrude from the elongated hole 36 of the sleeve 35.
This pin 37 is engaged with an engagement groove 38 formed at the upper end of the crank 31, and is made to protrude in the pushing direction by the biasing force of the spring 34. In this state, the canned waste 4 can be pushed out one by one by the product stocker 3 as a storage section.
9 and the lowermost cans 4 are pushed into the product stocker 3 by the tip of the pushing rod 32.
It is now impossible to exit from Exit 9. When the switch mechanism 8 becomes energized by inserting the coin 2, the shaft 22 rotates through the drive gear 19 and gears 20, 20a, and 21 due to the rotation of the motor 12, and while the conductive cam 15 rotates once, the cam 30 rotates. When the cam 30 makes one more rotation, during which the cam 30 comes into contact with the lower part of the crank 31 and presses it in the direction of the arrow in FIG. In this state, the lowermost can 4 in the product stocker 29 comes out of the outlet of the product stocker 29 and becomes ready to be pushed out. When the cam 30 comes out of contact with the crank 31 from this state, the crank 31
moves in the direction opposite to the direction of the arrow due to the biasing force of the spring 34 and pushes out the rod 32 via the pin 37.
is pushed out in the pushing direction, and only one canned youth 4 is dropped into the product take-out port 5. In addition, 40
is a positioning member for the can die 4. Further, the product stocker 39 is configured such that canned waste 4 can be put into the product stocker 39 through a refill port (not shown).

The change dispensing mechanism 10 is operated by a switch mechanism 8 when a coin 2 is inserted to send change 6 to a change return opening, and includes a crank pin 41 and a crank arm 42 that transmit the rotation of a motor 12.
and a pushing plate 43 as a feeding member that slides through the crank arm 42 and pushes out the change 6. The crank pin 41 is connected to the same shaft 22 as the conductive cam 22.
It is provided protruding from the side surface of a disk 47 arranged at the other end of the shaft 46 of a gear 45 that meshes with the gear 44 attached above. The crank arm 42 is rotatably supported at its lower end, and a long hole 48 formed in the crank arm 42 is connected to the crank pin 41.
is engaged with. The push-out plate 43 is housed in a casing 50 attached to the outlet of a change stocker 49 serving as a storage section, and has a pin 52 protruding from a long hole 51 provided at the bottom of the casing 50.
It is engaged with the upper end of the crank arm through.
Changes 6 are stored in a stack in a change stocker 49 and can be pushed out one by one by a push-out plate 43. Also, change stocker 49
Inside, change 6 can be replenished from a change replenishment port 53. The change replenishment port 53 is provided on the front side of the toy vending machine 1, but in some cases it may be better to provide it on the back side. Then, when the switch mechanism 8 becomes energized by inserting the coin 2, the rotation of the motor 12 rotates the shaft 22 via the drive gear 19 and gears 20, 20a, and 21, and the gear 4 on the shaft 22 rotates.
4 and a gear 45 meshing therewith, a shaft 46 rotates. Incidentally, 54a and 54b are gears for positioning the shaft 46, which are loosely fitted to the shaft 22 and are connected to the gears 21a and 55 on the shaft 21.
It meshes with. Next, the rotation of the shaft 46 causes the disk 47 to rotate, and the crank arm 42 is swung by the crank pin on the disk 47 and slides the push-out plate 43 to push out the change 6 from the outlet of the change stocker 49 and return the change to the change return opening 7.
Drop the change 6. In this case, the gear ratio of the gear 44 and the gear 45 is set to 3:1, and the disk 47 rotates three times during one rotation of the conductive cam 15, and the push-out plate 43 also reciprocates three times to push out three pieces of change 6. It's summery. That is, when one coin 2, which is a 100 yen coin, is inserted, one canned youth 4 will be dispensed, and three 10 yen coins 6 will be dispensed, giving you 30 yen in change.
The setting of the number of change 6 is not limited to the above example, and can be freely changed by setting the gear ratio of the gear 44 and the gear 45.

Although not shown, this vending machine toy 1 includes:
A coin receiving section is provided at the bottom so that it can be used as a savings box. Incidentally, the coin receiving section is set to be removable by a pull-out type or other means. Note that 60 is a product selection button.

Next, to explain the usage condition, first, when coin 2 is inserted into the coin slot 3, the switch mechanism 8
When the contact point 11 of
a, 21, at the same time that the conductive cam 15 begins to rotate via the shaft 22, the cam 23 rotates and comes into contact with the engagement piece 26, and the engagement plate 28 comes into contact with the protrusion piece 27, pushing the contact plate 11b apart and releasing the coin 2. to fall. In this state, the contact plate 18 and the conductive cam 15 are in contact with each other, so the contact 17
Even when the motor 12 is opened, the conduction to the motor 12 continues until the conductive cam 15 rotates once. Also, the motor 12
The rotation of the shaft 22 rotates as described above,
For every rotation of the conductive cam 15, the cam 30 also rotates once. Therefore, the crank 31 of the product delivery mechanism 9 is actuated by the rotation of the cam 30 to move the pushing rod 32 in and out, thereby pushing out one use can 4 and dropping it into the product outlet 5. In this case, the product is selected using the product selection button 60.
At the same time, the rotation of the gear 44 of the shaft 22 causes the disk 47 to rotate via the gear 45, and the crank pin 41 causes the crank arm 42 to swing. The push-out plate 43 slides back and forth due to the swinging of the crank arm 44, and the three pieces of change 6 are returned from the change stocker 49 to the change return port 7 during one rotation of the conductive cam 15. Then, when the conductive cam 15 rotates once, the contact 17 is opened, the current supply is stopped, and the device is ready for the next use.

[Effects of the invention] As explained above, the coin-operated switch mechanism of the toy of the present invention has the above-mentioned configuration, so it has a simple mechanism and can be used in toys operated by coin insertion, such as vending machine toys and piggy banks. The effect is that it can be made optimal and that it is possible to obtain enjoyment close to that of the actual thing.

In addition, by using an elastic body for one of the contacts of this switch mechanism, and making the contact open and close by a cam, etc. that interlocks with the energization maintenance mechanism to allow the coin to fall, a simple mechanism allows the motor to stop when the coin is inserted. You can perform the initial movement and collect coins thereafter.

Furthermore, the energization maintaining mechanism has a structure consisting of a conductive cam having a concave portion and a contact plate having a convex portion that faces the concave portion through a gap and slides around the conductive cam when it rotates, thereby simplifying the structure. This makes it possible to maintain electricity supply.
