BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toll collection telephone for paying a call charge by money or a prepaid card, and more particularly to a toll collection telephone having a handset connected by radio.

[0002]

2. Description of the Related Art A pink telephone provided in a coffee shop or a store is the same as a red commissioned public telephone in the mechanism itself in which a user pays a telephone charge by directly inserting the telephone charge into a coin slot of the telephone. . However, in the case of a commissioned public telephone, the telephone installation company directly collects the telephone charge from the telephone, whereas in the case of the pink telephone, the business owner installing the pink telephone pays the telephone installation company as a subscriber usage fee.

[0003] On the other hand, pink telephones are generally arranged at checkout places near entrances and exits. In recent years, in order to improve service for customers, the pink telephones have been wirelessly connected to a conventional telephone and a parent telephone. It is proposed to be a cordless telephone consisting of child units connected by lines,
Have been created. Therefore, the customer can make a call at his or her seat using the slave unit.

In such a toll collection telephone,
A sub-unit stand also serving as a charger is disposed near the parent unit, and usually the sub-unit is mounted on the sub-unit stand. When using the base phone, the user of the pink telephone lifts the handset of the base phone from the hook, inserts a coin into the coin insertion slot (or inserts a card into the card insertion slot), and then performs a dial operation. To initiate a call. When the call is finished and the handset is put on the hook, the coins charged more than the call charge are discharged to the coin return slot as remaining coins.

[0005] On the other hand, in the case of using the child device, the child device is picked up from the child device stand, coins are inserted into the coin insertion slot of the parent device, and then returned to a position near the parent device or to his / her own seat. Start a call by operating the dial keys of.

[0006] When the call is completed, the user presses a disconnect key provided near the dial key of the slave unit. Then, coins exceeding the call charge inserted into the coin insertion slot of the parent machine are discharged to the coin return slot as remaining coins.

[0007] However, such a toll collection telephone has the following problems. That is, the customer who uses the slave unit picks up the slave unit, and then inserts the number of coins into the coin slot of the master unit in consideration of the call destination and the talk time as described above. The inserted coins are temporarily stored in a storage track in the master unit. And the customer returns to his seat,
Operate the slave unit's dial key to initiate a call. When a call is started, a billing signal is transmitted from the station every time a predetermined time elapses according to the callee, and coins stored in the storage orbit are stored one by one in a safe.

In a state where one customer is talking using the slave unit at his / her own seat, the lamp indicating that the slave unit is in use is generally lit on the master unit and the vicinity of the master unit is near. Since the slave unit is not placed on the installed slave unit stand, another customer who came to the installation location of the master unit to make a call can confirm that the slave unit is in use. Is not used to make calls.

However, for customers who are unfamiliar with the pink telephone of this type or who need to make a rush call, lift the handset of the parent device and insert coins without confirming that the child device is in use. There is a case where a coin is inserted into a mouth and a dial key is executed. However, since the telephone line is connected to the handset, the tone signal cannot be heard even if the handset is put on the ear. Therefore, at this point, you notice that the slave is in use, but the coin inserted by this customer by mistake is considered to be the coin additionally inserted by the customer using the slave, so it is mistakenly inserted. These coins will not be returned to the wrong customer.

[0010] Therefore, there is a concern that a financial trouble may occur between the customer using the slave unit and the customer who has accidentally inserted coins. For this reason, conventionally, the opening / closing means is provided in the insertion slot so that another customer cannot insert money or a card into the insertion slot of the money or card of the parent machine during the use period of the child machine.

That is, as shown in FIGS. 6 and 7, an inlet gauge 2 is fixed to the housing 1 of the telephone. The insertion slot gauge 2 has a recessed insertion passage 2 for easy coin insertion.
a. The inserted coin falls into a coin orbit (not shown) formed on the substrate 3. A blocking lever 4 driven by a solenoid 3 is provided between the substrate 3 and the inlet gauge 2.

The blocking lever 4 is a U-shaped rod, and
Is rotatably mounted by a support shaft 5 between the end of the opening and the inlet gauge 2, and a spring 6 is used when the slave unit is not used.
, And is stopped by the stopper 7. For this reason, the blocking bar 4a at one end of the blocking lever 4 retreats from between the insertion port gauge 2 and the end of the substrate 3 to allow entry of coins. The other end 4b of the blocking lever 4 is rotatably attached to the cylinder 3a of the solenoid 3. Accordingly, when the solenoid 3 is energized and the cylinder 3a moves downward (in FIG. 7) by use of the slave unit, the blocking lever 4 rotates clockwise against the urging force of the spring 6 to rotate the blocking rod 4a. Enters between the inlet gauge 2 and the end of the substrate 3. For this reason, even if another customer tries to insert coins from the insertion slot gauge 2 without noticing during use of the slave unit, the coin is prevented.

[0013]

However, in the conventional opening / closing means having such a structure, the number of parts such as the blocking lever 4, the support shaft 5, the spring 6, and the stopper 7 is large, and the structure becomes complicated. In addition to the long inlet gauge 2, the blocking lever 4 is located between the inlet gauge 2 and the end of the substrate 3, so that a large installation space is required, which is an obstacle to downsizing the apparatus. An object of the present invention is to provide a toll collection telephone which eliminates such inconveniences, has a small number of articles, has a simple structure, and has a small installation space.

[0014]

In order to achieve the above object, in the toll collection telephone of the present invention, the opening / closing means for opening / closing the insertion opening of the housing is formed in a long columnar shape.
Center the axis along the longitudinal direction with the outer peripheral surface in close contact with the side
Rotatably attached to the center, the outer peripheral surface in the column radial direction
A shutter body having an opening that penetrates and matches the insertion opening and forms an insertion passage for money or a card with the insertion opening, and an angle at which the opening of the shutter body matches the insertion opening of the housing. The position and the angular position where the opening of the shutter body and the insertion opening of the housing do not coincide with each other and close the insertion opening on the outer peripheral surface of the shutter body.
And a driving means for driving the shutter body to rotate .

[0015]

In this manner, when the opening of the shutter body and the insertion opening of the housing coincide with each other, a coin or card insertion passage is formed by the two. Then, the shutter body is driven by the driving means, and the shutter body closes the insertion opening.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a housing 11 of a base unit of a telephone is provided with an insertion slot 12 for inserting coins. As shown in FIGS. 2 and 3, in the vicinity of the insertion port 12,
Guide frames 13a and 13b are fixed to the inner surface of the housing 11, and the guide frames 13a and 13b
The shutter plate 14 is slidably attached to the inner wall of the shutter plate 1 in a close contact state (for example, the ridges 15a and 15b on both sides of the shutter plate 14 are fitted to the guide frames 13a and 13b). In the shutter plate 14, an opening 14 a having the same size as the insertion port 12 is provided in parallel with the insertion port 12.

A base (not shown) fixed inside the housing 11 is energized when a slave unit wirelessly connected to the master unit is used, and is de-energized when the slave unit is released from use.
Has been fixed. A shutter plate 14 is attached to the tip of the cylinder 17a of the solenoid 17.

When the slave unit is not used, the shutter plate 14
The opening 14a is positioned so as to coincide with the insertion opening 12 of the housing 11 (the state shown in FIG. 1), thereby forming an insertion passage having a long depth. For this reason, when a coin is inserted from the insertion slot 12, the coin falls through the opening 14a into a coin orbit formed on the substrate 18.

When the slave unit is used, the solenoid 17 is energized, the cylinder 17a moves to the left (in FIG. 2), and the shutter plate 14 also moves integrally. Therefore, FIG.
As shown in (2), the opening 14a is shifted from the insertion port 12, and the insertion port 12 is closed by the shutter plate 14 in a sealed manner. Therefore, not only is the insertion of coins by other customers at the time of using the slave unit prevented, but also the insertion slot 12
Entry of dust, dust, water, and other foreign matter from inside the housing 11 is also prevented.

FIGS. 4 and 5 show another embodiment of the present invention. In this embodiment, a shutter cylinder 21 is rotatably mounted on a mounting bracket (not shown) fixed inside the housing 11 in close contact with the inside of the insertion opening 12 of the housing 11. The shutter cylinder 21 has an opening 21 a that has the same size as the insertion opening 12 of the housing 11 and that penetrates in the diameter direction.
Are provided in the axial direction. A solenoid (not shown) fixed inside the housing 11 is energized when the slave unit is used, and is de-energized when the slave unit is released from use.
2 is fixed.

The cylinder 22a of the solenoid 22
And a shutter cylinder 21 are connected by cranks 23 and 24, and a cylinder 22 driven by a solenoid 22.
The linear movement a is converted into a rotation of the shutter cylinder 21 by a predetermined angle.

For this reason, when the slave unit is not used, the opening 21a of the shutter cylinder 21 coincides with the insertion opening 12 of the housing 11, so that an insertion passage is formed by both, and when coins are inserted,
It falls on a coin orbit formed on a substrate (not shown).

When the slave unit is used, the solenoid 22
Is turned on, the shutter cylinder 21 is rotated by a predetermined angle by the cranks 23 and 24, and the insertion port 12 is closed in a closed manner by the shutter cylinder 21. Note that the insertion slot 12 can be closed not only when the slave unit is used but also when the telephone is out of order or during a call charge process for the previous call.

The present invention is not limited to the coin insertion slot,
It can also be applied to closing the card insertion slot. Also,
Although the example in which the insertion opening 12 and the openings 14a and 21a have the same size has been described, the size of the insertion opening 12 is set to be slightly larger than the inserted coin size (to prevent dimensional accuracy from being required), and the openings 14a and Only the dimension of 21a may be set to an accurate gauge dimension for preventing insertion of a coin larger than the diameter and thickness of regular coins.

In addition, even when the handset is not used, except when the handset is lifted from the hook, the shutter plate 14 or the column 2 is used to prevent the entry of dust and the like from the insertion slot 12.
You may make it block with 1.
