Description

Photo printer with replaceable connectivity modules

technical field

The invention relates to a photo printer, in particular to a photo printer with a conveniently replaceable connection module.

Background technique

With the rapid development of digital technology, the low price and portability of portable digital image capture devices such as mobile phones and digital cameras have also made these devices a part of modern people's lives. In order to store the dynamic and static images captured by these image capture devices, a flash memory card (Compact Flash card, CF card) has become one of the commonly used storage media. The flash memory card stores captured images in a digital file format (such as a JPG format). Afterwards, the flash memory card with these images stored therein is connected to a computer for further image processing and even enhancement of special effects. Of course, these images can also be connected to a photo printer (Photo Printer) to directly print these images into lifelike patterns.

Please refer to FIG. 1 . FIG. 1 is a schematic diagram of the connection between the slot 22 and the connector 14 of the conventional flash memory card 20 . Printer 10 includes a circuit board 12 that includes a connector 14 . The connector 14 includes a set of conductive terminals 16 for connecting with the slot 22 of the flash memory card 20, so that the data stored in the flash memory card 20 can be transmitted to the control circuit on the circuit board 12 via the conductive terminals 16 for further processing.

Generally speaking, because the slot 22 and the connector 14 of the flash memory card 20 are parts that are often plugged in and out, and the mutual connection positions of the two have fixed requirements, that is to say, special attention should be paid to the connection between the two. Whether the slot 22 is aligned with the conductive terminal 16 of the connector 14 or not, only if they are aligned, can the two be connected smoothly. However, some careless users connect the socket 22 and the connector 14 with each other in a rough manner when they are not aligned, which can easily cause the conductive terminals 16 to break due to improper external force. Once the conductive terminal 16 is broken, if the connector 14 needs to be replaced, the entire printer 10 must be disassembled to replace the damaged connector 14 . This is a very inconvenient thing for users.

Contents of the invention

Therefore, an object of the present invention is to provide a printer with an easily replaceable connection module to solve the above problems.

The object of the present invention is achieved in that a photo printer is provided, which includes a housing; a circuit board installed in the housing, on which a control circuit and a first group of female conductive terminals are provided, the control circuit Used to control the operation of the printer; a connection module, which includes an adapter and a shell, used to accommodate the adapter, and the shell is fixed on the circuit board, the adapter includes a first set of male Conductive terminals and a second group of male conductive terminals, the first group of male conductive terminals is used to connect the first group of female conductive terminals; an external card for storing data, the external card includes a second group of female conductive terminals, Used to connect the second group of male conductive terminals.

The advantage of the present invention is that in the process of connecting the female conductive terminal of the external card to the male conductive terminal, it is easy to cause the male conductive terminal to break due to improper force, but the connection module of the present invention has two sets of male conductive terminals, one One can be plugged and connected with the first group of female conductive terminals on the circuit board, and the other can be plugged and connected with the second group of female conductive terminals of the external card, so even if the external card is improperly applied during the plugging process , causing the second group of male conductive terminals corresponding to the connection module to break, the user can quickly remove the connection module from the housing and replace it with a new connection module.

Detailed ways

Please refer to FIG. 2 and FIG. 3 , FIG. 2 is a schematic diagram of the appearance of the photo printer 30 of the present invention, and FIG. 3 is a schematic diagram of the interior of the photo printer 30 of FIG. 2 . The printer 30 includes a casing 32 , a circuit board 12 , a dust-proof component 42 , a connection module 40 and an external card 36 . The circuit board 34 is installed in the housing 32 and has a control circuit (not shown) and a first set of female conductive terminals 56 on it. The control circuit is used to control the operation of the printer 30 . The connection module 40 includes an adapter 48 and a housing 60. The adapter 48 includes a first group of male conductive terminals 50 and a second group of male conductive terminals 52. The first group of male conductive terminals 50 is used to connect the first group of The female conductive terminal 56 and the housing 60 are used to accommodate the adapter 48 . The external card 36 is used to store data, which can be a flash memory card or other similar memory cards. The external card 36 includes a second group of female conductive terminals 58 for connecting to the second group of male conductive terminals 52 . The dustproof member 42 covers the casing 32 to prevent dust from floating into the interior of the printer 30 .

In order to further illustrate the connection relationship between the connection module 40 of this embodiment, the external card 36 and the circuit board 12, please refer to FIG. 2, FIG. 3 and FIG. Schematic of plate 12. The adapter 48 includes two extensions 90 , each of which has a first opening 92 .
