Abstract: The present invention utilizes the cooperation between vowel letter surfaces on single vowel cubes and the letter surface on single consonant cubes to achieve a spelling practice of English vocabularies. By concurrently throwing or reversing one or several single vowel cubes and the single consonant cubes, the settled vowel letter surface and the letter surface facing upward further offer other phonetic practice. A serial vowel area and a serial consonant area on the single vowel cube and on the single consonant cube could help users swiftly find the letters. Serial numbers on each of the single vowel cubes and on each of the single consonant cubes are served for a speedy placement. Such teaching aid has a simple structure and low manufacturing cost. Moreover, since there are letters presented on each side of the cubes, a diverse arrangement is achieved. The present invention accomplishes a convenient utilization and diverse functions.

Abstract: The invention relates to a latch device for engaging with a keyboard within a housing of a portable electronic apparatus. The latch device includes a support, a latch, and a saw-toothed elastic strip. The support is connected with the housing, and a portion of the latch stretches out from the housing to engage with the keyboard. Two ends of the first saw-toothed elastic strip connect respectively with the support and the latch. The latch moves relatively toward the support by using the first saw-toothed elastic strip. The keyboard can be detached from the housing when an external force presses the latch into the housing. Moreover, because of the deformation of the first saw-toothed elastic strip, the first saw-toothed elastic strip provides a recovering force to press a portion of the latch out of the housing.
