[0032] As Figure 6 、 7As shown, in some specific embodiments, the housing mechanism 10 includes a housing structure 11 and a mounting frame 12 disposed within the housing structure 11. The housing structure 11 and the mounting frame 12 surround to form the installation chamber. The mounting frame 12 includes a first mounting plate 121 and a second mounting plate 122 oppositely disposed on both sides. A telescopic channel for mounting the paper output mechanism 50 is formed by surrounding between the first mounting plate 121, the second mounting plate 122 and the housing structure 11.
