[Embodiment of the invention]

 As shown in FIGS. 1 and 2, the PDA having a printing function of the present invention has a printing device 2 and a paper feed tray 3 connected to a PDA 1.

The PDA 1 includes a CPU, a display 13, and a power supply device, and since the components and principles of the PDA 1 are similar to well-known products, description thereof will be omitted.

A display 13 and a paper feed slit 110 are provided in the upper case 11, and the paper feed slit 110 is provided corresponding to a paper output position of the printing apparatus 2.

The printing device 2 is provided inside the upper case 11, a thermal head 21 and transport wheels 23 and 231 are provided in the printing device 2, and a sensor 24 is provided at a paper output portion of the thermal head 21. Have been. A fitting groove 121 is provided in a portion of the lower case 12 corresponding to the lower side of the printing device 2, and the paper feed tray 3 is fitted inside the fitting groove 121. This is as shown in FIGS.

As shown in FIGS. 2 and 3, the structure of the paper feed tray 3 is provided so as to correspond to the fitting groove 121, and a storage space 30 is provided in the paper feed tray 3. A plate 31 and a spring 32 are provided. The paper 4 is stored in the storage space 30, and the entire paper 4 is kept urged forward by the combination of the spring 32 by the push plate 31.

A transport wheel 22 is provided in the lower case 12 corresponding to a portion of the paper tray 3 on which paper is to be placed, and the transport wheel 22 is driven by a stepping motor. Press against paper 4.

The paper 4 adopted in the present invention is a single-piece type and is a laminated thermal paper. The capacity of the paper in the paper feed tray 3 is set to approximately 100 sheets.
